I have had a few that I thought would rock on the shave but not so much. I think most times it is because I have gone too far, or in the case of stainless used too much pressure while honing, especially on the 1K and 4K. Just a theory. I have to check it over a longer period before I really buy into it, but a well known member here suggested it to me so it is very likely the truth and initially it looks like a viable theory.
